The science

How Lulu opens the doorway.

Your brain settles into slow Delta and Theta waves during deep sleep. Lulu's light patterns are calibrated to mirror those frequencies — triggering the frequency-follow response, so your brain gently synchronises and shifts into sleep as if it were already there.

01

Close your eyes

Prop your phone with the flash facing you, or lay it flat to reflect off the ceiling. Choose your sound. Then let go.

02

Precise pulses of light

Powerful enough to guide your brain through closed eyelids. Comfortable enough to drift off in. Your eyes stay closed.

03

Sleep arrives naturally

Once you enter hypnagogia, sleep follows on its own. Lulu switches itself off. No alarms. No disruptions. Just sleep.

The experience

The next revolution in sleep.

Sleep on demand
Sleep on demand

No more watching the clock.

No more laying there. No more negotiating with your own mind. A Lulu session takes just 15 minutes — many people don't make it to the end. Choose your sound, close your eyes, and let the light do the rest.

Power naps that work
Power naps that work

The reset your day needed.

Not all naps are created equal. The Lulu Power Nap is a 21-minute guided experience. Precise pulses ease you into deep relaxation, then gently bring you back — alert and refreshed, right on cue.

Beat the jet lag

New city? Wrong timezone? Wide awake at 3am? Lulu helps your body adjust to a new timezone faster — so you spend less time struggling and more time present.

Lulu on the nightstand
Built in London · Founded 2022

A sleep app built around hypnagogia.

Hypnagogia is the name for the halfway state between wakefulness and sleep — the threshold you cross every single night on the way to falling asleep.

Lulu uses specific frequencies of light from your phone's flashlight to guide you into that state within a few minutes. No training. No equipment. Just you, your phone, and a dark room.

Works for creative minds, anxious minds, and restless minds. If your mind won't stop at night, Lulu was practically made for you.
